TILL'IAM M. SLOANE, OF BUFFALO, NEW YORK.

MACHINE FOR DRESSING STAVES.

Specification of Letters Patent No. 27,161, dated February 14, 1860.

To all whom 'it may concern.'

Be it known that I, WVM. M. SLoANn, of the city of Buffalo, county of Erie, and State of New York, have invented certain new and useful Improvements in Stave- Dressing Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure I is a side elevation. Fig. IT is a plan. Fig. Ill is a side elevation in diagram of the rotating bed and feed and pressure rollers. Fig. TV is a plan of former. Fig. V is a cross section of same. Fig. Vl is a section of the rotating bed and the friction rollers which support it.

Like letters refer to like parts in each of the figures.

A is the main frame of the machine sup ported upon the bed or foundation (A).

B is an annular rim forming a rotating bed upon which the stave is carried from the guide feed rollers, to the cutters which dress the edges of the stave to the required bilge and bevel. The surface of the rotating bed is roughened so that it will carry the stave between the pressure rollers and thus avoid the necessity of gearing them, which it would be necessary to do were the surface of the rotating bed smooth.

(C) are cogs placed upon the inner circumference of the rotating bed (B) and by which motion is given thereto. Y

(D) are two annular flanges one on each side of the rotating bed (B) at or near the base of the cogs (O).

E, FX, E2 are friction rollers placed upon the shafts F, F', and F2, which shafts have journal bearings in the main frame. The annular flanges (D) rest upon these friction rollers, there being two on each shaft F, F, and F2, arranged on each side of the cogs (O) so that said cogs will run between them and the flanges l) upon them. The shaft (F) and rollers (E) are placed on a vertical line passing through the center of the rotating bed, the rollers E and E2 being arranged on either side at proper distances to insure a steady movement to the rotating bed. This arrangement of the friction rollers and annular flanges is more particularly shown in Fig. VI.

(Gr) is a vertically moving frame in which are placed the revolving cutters which dress the edges of the staves.

" H, are guide rods which guide the frame (Gr) in its vertical movement.

l, I, are cams of a peculiar form placed upon the shaft F and by which the frame (Gr) is given its proper vertical movement.

(J, J,) are the cutters which dress the edges of the stave to the required bilge and bevel. K, K, are the shafts upon which these cutters are placed. (L, L), driving pulleys upon the extremities of the shafts (K). M, M journal boxes in which the cutter shafts (K) revolve. These boxes are adjustable in slots in the frame (G) so that the cutters may be adjusted to different width of staves and different sizes of barrels. N and O, ,j

feed rollers which feed the stave to the rotating bed which carries it between the pressure rollers to the cutters (J). P', shaft on which the roller (N) is placed. P adjustable journal boxes in which the shaft (P) revolves. These boxes are placed between the jaws p and are moved by the screws p2 and p3 to adjust the distance between the rollers N and O, according to the thickness of the stave to be dressed.

a, is an adjustable stop placed on the roller (N). Its arrangement in relation to the cutters (J) will be hereinafter more fully described. (Q), table 0n which the stave is placed in order to be fed to the cut ters (Q), gage placed on table (Q) to insure the proper introduction of the stave to the machine. (R), horizontal cutters which plane the outer surface of the stave and bring it to the required thickness. (R), shaft upon which the cutters (R) are placed. This shaft turns in adjustable journal boxes (1) which are adjusted by the screws (r) according to the thickness of the stave to be planed. (r2), driving pulley on shaft (R). (S), pressure rollers placed on each side of the cutters (R) to hold thestave while the cutters are acting upon it.. These rollers also have adjustable journal boxes (8') adjusted by the screws (s2). s3 rubber springs which allow the movement necessary in cutting staves of slightly different thickness. T and T, pressure rollers arranged at equal distances on each side of the cutters (J). U, adjustable journal boxes in which the shafts T2 of the upper pressure rollers T revolve. u and u', adjusting screws. u2,

rubber springs which allow the movement necessary in passing staves of slightly different thickness between them.

The surfaces of the upper pressure rollers T are concave, Vthe degree of concavity increasing' in the successive rollers so that the stave will not be bent too suddenly in giving it its transverse curve. Y

The under rollers (T) are arranged on each side of the rotating bed. lThey have journal bearings on the main frame as shown at (t) and in the brackets (t2) :projecting inward from the main frame. The two rollers on oppositefsides of thefrota'ting bedand whose shafts are on the same line taken together are convex to a degree corresponding to the degree of concavity of the upper rollers T. V, former which holds the stave to the bed while the cutters (J) are acting upon it and with the pressure rollers T, T, gives it its curved form, both transverse and longitudinal. o', screws by which the former is adjusted for staves of different thickness. o2, rubber strings to allow th-e former to yield iu passing through staves of slightly different thickness. v3 slides by which the width of the former may be regulated to different widths of staves. v4, bolts by which the slides are held in place.

W is the driving pulley which gives motion to the rotating bed and feed rollers.

is a pinion on the same shaft which drives the spur wheel fw2 on shaft (F). The cams I, I, also on 'this shaft will by their action give the proper vertical movementto the frame G and cutters (J).

The pinion placed between the friction rollers F, and meshing with the cogs (C) will give the proper movement to the rotating feed bed. The spur wheels (Y and Z) on the extremities of the shafts of the rollers (N, 0,) gear together and by the transmitting spur wheels X Y Z will give the proper motion to the feed rollers (N O). The roller (N) has a circumference equal at least to the length of the longest stave. The stop is so arranged upon the roller (N) and the gearing for driving said roller so proportioned that the stave Where its end is placed against the stop, its middle or Widest part will be brought to the action of the cutter (J) at the time when the cutters are at the lowest part of their vertical movement. When a shorter stave is to be dressed the stop (n) is moved back half the difference between its length and that of the longby the rotating est stave, so as to bring itsmiddle or widest part to the `actionof 'thecutters in the relative position before described.

. I Operation: The stave being heated by any .proper'means, is laid on the table Q-its side against the gage Q and its end against the stop (n). The feed rollers N, O, will carry it tothe planer "(R) which will dress the outer surface. It will then be carried bed between v the .pressure rollers and under thefformer, receiving its proper bilge and bevel from the cutters (J) and be carried from the machine finished, that is, planed, jointed and with its proper curves or nearly so.

For a more. particular description of the construction and operation of cams I, I, and cutters J reference is made to a patent granted to me the 29th of June, 1858, for improvements in stavey machines.

1. I claim the feed roller (N) having the gage (n) in combination with the cutters (J J) when the said feed roller is so placed and arranged with reference to the cutters and other parts' of the machine, as that the stave will be fedto the cutters, in such relative time and motion, as to cause the middle of the stave to be dressed, while the cuttersk are in their lowest position, substantially as herein described.

2. I claim the combination and arrangement of the gage stave to be dressed, the said gage being adjustable on the face of the roller so as to cause the middle of a long or short stave to be dressed by the cutters while in their lowest position substantially as set forth.

3. I claim the relative arrangement of the annular rim or feed bed (B) friction rollers (E E and E2) and pressure rollers (T T) for the purpose set forth.

Y 4. I claim the combination of the rotating a roughened surface with the bed havin pressure ro 1ers (T and T) for the purposes and substantially as herein described.
